I am making a server-based gaming PC for the purpose of being able to host large local servers, what kind of SSD would be best for the job?

I am making a server-based gaming rig for the purpose of hosting large local game servers and playing on them at the same time, and I know high speed storage is important but what would be best? The Higher capacities of SATA SSD's, Slightly lower capacity NVMe/PCIe SSD's with a lot of raw bandwidth, or the technologies offered by Intel Optane (3D Xpoint)

EDIT: NVM my solution does not support optane

Needed to remove intel optane because my hardware does not support it

Use optane to cache a sata or use storeMI to use a nvme and sata.

How is that helpful in the realm of large local game servers?
